CleanSpark Issues August 2023 Bitcoin Mining Update

CleanSpark, Inc. (Nasdaq: CLSK), America's Bitcoin Miner™, today released its unaudited bitcoin mining and operations update for the month ending August 31, 2023.

"August was another banner month for CleanSpark as the 50MW expansion in Washington saw its first full month at maximum operational hashrate, delivering some of our highest daily production ever," said CleanSpark CEO Zach Bradford. "What's more, we have carefully managed power to achieve substantially high levels of uptime in August, despite historically high levels of rain and very hot weather. That operational prowess has resulted in what we expect is among the best monthly bitcoin production rates of publicly traded miners in North America."

August Bitcoin Mining Update (unaudited)

• Bitcoin mined in August: 659
• CY2023 bitcoin mined: 4,729
• Total BTC holdings as of August 31: 1,677
• Total BTC sold in August: 43
• Deployed fleet: 88,217
• Month-end fleet efficiency: 28.7
• Current hashrate: 9.3 EH/s

The Company sold 43 bitcoins in August 2023 at an average of approximately $28,200 per BTC. Sales of BTC equated to proceeds of approximately $1.2 million. August daily BTC mined averaged 21.26 and reached a high of 22.11.

Operational updates

Sandersville. Construction is underway at the Company's newest expansion in Sandersville, GA. Concrete has been poured for Building 1, and construction on subsequent buildings begins this week. Materials are arriving on site daily and all ten data centers are expected to be completed later this year. Once finished, the site will be home to 230MW of the most efficient bitcoin mining machines available, making it one of the largest bitcoin mining data centers in the southeastern United States. The expansion itself is 150MW and is expected to house 45,000 miners.

Concurrently, the Municipal Energy Authority of Georgia (MEAG) has been constructing a 200MW substation and related infrastructure that will power the Sandersville expansion. The utility has informed the Company that it expects to complete the substation in 2023, but the related power-line project that connects to the substation is expected to push into early 2024, after which time miners will be promptly energized to achieve CleanSpark's target of 16 EH/s of operational hashrate.

Additional commentary about the Sandersville expansion, including recent photos, are available here and here.
